Eminem to quit

The rapper's D12 bandmate Proof claims the 'Just Lose It' singer is ready to turn his back on performing and recording for good at the end of his current 'Anger Management' tour.

He said: "Em has definitely got to the level where he feels like he's accomplished everything he can accomplish in rap."

Proof claims Eminem - real name Marshall Mathers - is making the shock decision so he can concentrate on producing other artists.

He added in an interview with the Detroit Free Press: "He wants to kick back and get into the producing thing. Why not bow out while you're on top?"

Eminem's spokesperson has so far refused to confirm whether or not the star is about to retire, but Jeff Bass - the Detroit producer who co-wrote Eminem's hit single 'Lose Yourself' - claims the rapper could release music under an alias.

Bass said: "The Eminem part of his career isn't going to be at the forefront anymore."

The 33-year-old star is the biggest-selling rap artist of all time - his 2000 album 'The Marshall Mathers LP' sold an incredible 9.8million copies.

However, in recent months the star has wanted to spend more time with daughter Hailie.
